iPhoto organises my photos by date which would be great if all my photos had correct dates/times on them. The images direct from digital camera are obviously fine, but those I've scanned or had processed digitally at the lab and then entered have incorrect dates and times - messing everything up!

So I'd like to edit this metadata to clear these probs up. Anybody know how?

Click on the photo, click the 'i' button in the bottom left to show info, and then you can edit the date/time/title.
For more than one photo; select the ones you wish to edit the data for, choose "Batch change..." from the "Photo" menu and then select "date" from the drop-down menu. There you can set all of them to have the same date, but add 5 mins to the time for each photo, or whatever you want.
